Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wig caps often cause hair breakage, thinning, and excessive wig slippage due to inadequate fit and material, which can expose the natural hairline and fail to provide a secure, comfortable wear.

Innovation Solution

A wig kit comprising a customizable wig cap with sew-on snap fasteners and an elastic band, utilizing breathable fabrics like nylon and knit, with snap fasteners made of metal or plastic, ensuring a secure and comfortable fit by distributing pressure evenly and allowing for adjustable sizes and colors to match individual skin tones.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wig cap is made thicker to provide better coverage and protection, then the security and protection against hair breakage is improved, but the wearer's head is exposed to extreme heat and comfort is reduced

Engineering Contradiction:

Improvewig security and hair protectionVSAvoidheat exposure to wearer's head

Core Design Contradiction:

ReliabilityVSTemperature

Solution Approach 1:

The wig cap is divided into multiple layers with different functions: an inner layer for comfort and breathability, and an outer layer for security and protection. This segmentation allows each layer to optimize its specific function without compromising the other.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wig cap uses composite material construction combining breathable fabrics (nylon, knit) with secure fastening systems (snap fasteners). This composite approach provides both the security needed to prevent hair breakage and the breathability needed to reduce heat exposure.

Inventive Principle:

Principle #40Composite materials

2Temperature

If a wig cap is made thinner to provide better breathability and comfort, then heat exposure is reduced, but the wig becomes less secure and may slip or move excessively

Engineering Contradiction:

Improveheat exposure and breathabilityVSAvoidwig security and stability

Core Design Contradiction:

TemperatureVSReliability

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The snap fastener system acts as an intermediary mechanism that provides secure attachment without requiring excessive friction or pressure from the cap material itself, allowing thin breathable materials to still achieve reliable wig retention.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of manufacture

If adjustable tension springs or straps are used to achieve a one-size-fits-all fit, then manufacturing simplicity is improved, but the fit may cause hair breakage and thinning at the edges

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidhair breakage and thinning

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The wig cap offers adjustable sizing options (small, medium, large, extra large) that allow customization of fit parameters. This enables optimal fit for different head sizes without requiring excessive tension that would cause hair damage.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The snap fastener system provides localized adjustment capabilities at specific points around the head, allowing precise fit control without applying excessive uniform tension that would damage hair at the edges.

Inventive Principle:

Principle #3Local quality

4Ease of manufacture

If visible fasteners are used to secure the wig, then manufacturing simplicity is improved, but the natural appearance of the hairline is compromised

Engineering Contradiction:

Improvefastening simplicityVSAvoidnatural appearance of hairline

Core Design Contradiction:

Ease of manufactureVSShape

Solution Approach 1:

The visible portion of the fastener mechanism is extracted or concealed within the cap structure, leaving only minimal invisible elements at the hairline. This maintains the natural appearance while preserving the secure fastening function.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The invention concerns a wig or lace wig cap, to be worn by the user underneath a wig or lace wig. The cap is comprised of a plurality of panels using stretchable and breathable material, an elasticized banding and a plurality of sew on snap fasteners affixed to, said banding to form the Press and Go Wig and Lace Wig Snap Cap. Cooperating snaps are then affixed to a wig or lace wig around the entire circumference of the outer inside wig weft, concealing the application process, thereby producing a comfortable, airy and secure fit to the user. An additional banding is included, affixed with a plurality of snap fasteners designed to fit cooperating snaps of a wig or lace wig. Also included is a tension strap affixed with two cooperating snap fasteners designed to be used as an adjustment strap to the cap banding or separate banding.
